Acid Yellow 17 (CAS 6359-98-4) is a highly versatile dye intermediate, finding application across a surprisingly broad spectrum of industries. While its primary utility lies in the vibrant yellow hues it imparts to textiles, its properties make it valuable in leather finishing, paper manufacturing, and even in certain formulations within the paint, pharmaceutical, and cosmetic sectors. For procurement managers and formulators seeking a reliable source, understanding these diverse applications is key. NINGBO INNO PHARMCHEM CO.,LTD. is a premier manufacturer and supplier that caters to these varied industrial demands.

Textile Industry: The Primary Domain

The most significant application of Acid Yellow 17 is in the dyeing of protein fibers such as wool and silk, as well as synthetic polyamide fibers like nylon. Its acidic nature allows it to form strong ionic bonds with the amine groups in these fibers, resulting in excellent color fastness, especially lightfastness. Textile manufacturers value its bright yellow shade and good leveling properties, which ensure uniform dyeing. Purchasing this dye intermediate from a quality supplier like NINGBO INNO PHARMCHEM CO.,LTD. guarantees the consistency needed for mass production.

Leather and Paper Applications

In the leather industry, Acid Yellow 17 is used for surface coloring, providing attractive and durable yellow tones for various leather goods. Its ability to achieve a good shade depth and consistent color penetration is highly valued. Similarly, in the paper industry, it serves for paper shading, enhancing the visual appeal of paper products. The dye's high solubility ensures it can be easily integrated into paper pulp or surface coating formulations.

Emerging and Niche Applications

Beyond its traditional uses, Acid Yellow 17 can also be found in other industrial applications:

  • Paints: It can be used as a colorant in certain types of paints and coatings, offering a bright yellow pigment.
  • Pharmaceuticals: In specific instances, dyes with high purity and rigorous testing can be employed for coloring pharmaceutical tablets or capsules, although regulatory approval is paramount.
  • Cosmetics: Similarly, certain cosmetic formulations may utilize carefully approved dyes for coloration, with Acid Yellow 17 being a potential candidate depending on strict regulatory compliance.

Sourcing Quality Acid Yellow 17

For any of these applications, securing a high-quality, consistent supply of Acid Yellow 17 is crucial. When looking to buy, consider:

  • Purity and Specifications: Ensure the product meets required purity standards (low insolubles, controlled moisture) and consistent strength/shade.
  • Supplier Reliability: Partner with a manufacturer that offers dependable service, technical support, and competitive pricing.
  • Regulatory Compliance: Especially for pharmaceutical and cosmetic applications, verify that the specific grade of Acid Yellow 17 meets all relevant regulatory requirements.

By understanding the diverse applications of Acid Yellow 17 and choosing a quality supplier like NINGBO INNO PHARMCHEM CO.,LTD., businesses can effectively harness its coloring capabilities across various industrial landscapes.
